In my experience, use of vtables is relatively rare in modern C++ development even when you aren't trying to avoid them, many of which are elided by the compiler anyway. Regardless, in these infrequent cases it is straightforward to code equivalent functionality without vtables, since it is syntactic type-safe sugar over the code you'd have to write in C anyway. They are like C bitfields in that every systems programmer knows how to implement the equivalent functionality manually for cases when the language feature is underspecified for the purpose. Modern C++ without vtables is only marginally different than modern C++ with vtables, the code you'd write and the features you'd use would be nearly unchanged.
